Spatial Prediction of Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) in European Soils
Open accessAbstract
High Resolution Image Download MS PowerPoint Slide Currently, little is known about the spatial distribution of per- and polyfluoroalkyl substances (PFAS) in soils. In this study, machine learning was applied to a data set from the Map of Forever Pollution in Europe (MFPE) containing 6697 scattered PFAS soil concentration measurements to comprehensively predict PFAS concentrations in European soils. The model is based on a regression analysis between the PFAS soil concentrations and the distance to presumptive point sources indicated by the MFPE. Generally, decreasing PFAS concentrations were observed with increasing distances to the nearest point sources. Subsequently, on the basis of the regression analysis, a map was generated showing the PFAS concentrations in European soils by interpolating the model predictions at 10 000 random spots where no measurements were available. The map revealed that a significant portion of European soils is potentially contaminated with PFAS at concentrations of >5000 ng/kg. At this concentration, the mobilization of PFAS can lead to seepage water concentrations of 2–5 ng/L surpassing current and proposed drinking water guidelines in Europe. This illustrates the need for lower PFAS soil threshold values. Overall, the produced map provides, for the first time, comprehensive information about European PFAS soil contamination and serves as a basis for assessing its environmental risks.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
